The versatile EZ-USB HX3 USB 3.0 hub controller offers full configurability via I2C EEPROM, I2C Slave and GPIO options, allowing designers to configure PHY drive strength, the number of downstream ports, power switch polarity, LED indicators and more. HX3 offers a Ghost Charging feature for charging of devices without a host, and it also supports the USB-IF Battery Charging v1.2 specification and charging of Apple devices. HX3 is the first SuperSpeed USB (USB 3.0) hub controller to offer an Accessory Charger Adaptor Dock (ACA-Dock) feature, which enables upstream charging for portable devices with a USB On-The-Go (OTG) host. The controller’s Shared Link feature enables up to eight downstream ports, allowing products such as docking stations and desktop monitors to connect with more USB peripherals using a single four port hub. HX3 is highly interoperable and has been thoroughly tested against over 400 USB peripherals, including popular consumer electronics, PC peripherals, HDDs and SSDs, and legacy devices.

“The widely available USB 3.0 ports in personal computers are now beginning to show up on mobile devices such as tablets and smart phones,” said Mark Fu, Senior Director of the USB 3.0 Business Unit at Cypress. “Product designers want USB 3.0 port expansion solutions that are smaller and more power-efficient to achieve further miniaturization and lower power consumption for their mobile designs. Our HX3 controller’s space-saving 6 mm x 6 mm package helps product designers achieve this goal, providing design flexibility, low power and top performance in a tiny package. We are working on an even smaller 10-mm2 chip-scale package option that will further drive down the HX3 solution footprint by another 70%.”

The EZ-USB HX3 hub controller’s on-chip USB 2.0 and SuperSpeed PHYs are each configurable, which helps to preserve signal integrity when driving long PCB traces. Its High-speed slope, Transmit Amplitude, and De-emphasis parameters are adjustable from a Graphical User Interface on a PC. HX3 consumes only 40 mW in standby mode and 735 mW with all ports in operation at SuperSpeed data rates—50% less than competing solutions.

Product Availability

Cypress is now sampling three versions of the EZ-USB HX3 USB 3.0 hub controller in the new BGA package: the CYUSB3328 4-port hub with Shared Link and GPIO interface, the CYUSB3314 4-port hub with individual port power control, and the CYUSB3304 4-port hub with ganged port power control. More information on HX3 is available at www.cypress.com/hx3.

Three EZ-USB HX3 Development Kits are available for customer evaluation: the full-featured CY4613 with the CYUSB3328 controller, the versatile CY4603 with the CYUSB3314 controller, and the low-BOM CY4609 with the CYUSB3304 controller. These kits integrate the required external components and come with the Blaster Plus software utility for Windows, which is used to change the configuration parameters of the HX3.

EZ-USB FX3 provides SuperSpeed USB (USB 3.0) connectivity in virtually any system. It is equipped with a highly configurable General Programmable Interface (GPIF™ II), which can be programmed in 8-, 16- and 32-bit configurations with data rates as high as 400 megabytes per second. GPIF II enables FX3 to interface directly to nearly any processor, ASIC or FPGA. The on-chip ARM9 CPU core with 512 KB RAM delivers 200 MIPS of computational power and is available for applications that require local data processing.
